Unformatted text preview: have a minimum energy of E ≥ E a , the activation energy. • Activation energy is the minimum energy required for reactants to react in order to convert into products (via a transition state or activated complex). • Transition state is an unstable arrangement in which the bonds are in the process of being broken and formed and presents the maximum point on a potential energy diagram; it can not be isolated. Factors that Influence Rates of Reactions • Increase in concentration: Greater number of particles per unit volume per time means greater frequency of collisions and faster rate. • Increase in temperature: This causes an increase in average kinetic energy; particles collide more frequently and more forcefully. Thus number of particles with E ≥ E a increases greatly and rate increases (more forceful collisions is a more important...
